Greying of Hair: Why Hair Turns Grey
Hair derives its colour from granules of
melanin pigment produced by cells in the hair
follicle. With age melanocyte cells become
less active and what look like grey hairs start
to appear.
In fact the "grey" is a combination
of normally pigmented hairs interspersed
with white ones. Hair colour eventually turns
completely white when the melanocytes cease
to function altogether.
Nutrition and stress also affect hair colour.
Stress burns up B vitamins in the body, as docs
alcohol. A diet insufficient in these vitamins may
also hasten the appearance of grey hairs.
According to celebrity trichologist Philip
Kingsley, studies have shown that large doses of B
vitamins can reverse greying in three months.
Stop taking the vitamins and the graying of hair starts
again. Check with your doctor before starting a
course of nutritional supplements.
